|Galvanic time release is a device to avoid ghost fishing by pots left or lost in open sea. It is manufactured by inserting plated wire eyes (cathodes) into precisely machined cylinders of a highly active metal alloy (anode).|
|The Galvanic Timed Release is quite simple with only 3 components (two cathodes and one anode). When the GTR is placed in an electrolyte such as seawater the cathodes, being plated with a more passive or noble metal, cause the cylinder of more anodic or active material to electrochemically degrade, evolving hydrogen gas (visibly). |
The operation costs for GTR mechanism is minimal and the industry is usining it more and more to prevent ghost fishing by pots.
